Not Right For WatchKnowLearn

WatchKnowLearn ratings are intentionally harsher than what you might find on YouTube, for example.
Most of our videos have been imported by people who want to use them with kids, not by the creators of the videos.
We take a hard-nosed attitude toward quality. Four and five stars should be reserved for really excellent quality.
Three stars isn't bad. Two is often watchable and shouldn't be ruled out.

5 stars = Exemplary.
Unusually helpful and well produced. Do not overuse this, please; it is not the standard rating for decent work,
as it is elsewhere.

4 stars = Very Good.
Very helpful but not among the very best; adequately produced, at least.

3 stars = Usable.
Reasonably helpful, perhaps a bit amateurish in production or has some other problem; there is nothing wrong with
a 3-star rating for amateur work!

2 stars = Some Merit.
Minimally helpful; not completely worthless or inappropriate; you can see how it might be useful to some people.

1 star = Not Right for WatchKnowLearn.
Not at all helpful, not educational, poorest quality, etc.; you can't see it being useful to anyone.

The Chesapeake Bay receives water from the 64,000 square miles of land surrounding the bay and Landsat satellites are a critical and invaluable tool for characterizing the landscape and mapping it over time. Landsat data provides a baseline of observations for science about how human activities on the land affect water quality, affect wildlife habitat, affect air quality. Without it we wouldn't be able to really understand how sources of nutrients and sediment have changed and where they are in the Chesapeake Bay. (04:27) The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey.

Unless changed, the Finder is the person who uploaded the video to WatchKnowLearn.

The Finder is allowed to "lock" information about the Owner and Producer (so other accounts cannot edit this information).
The Finder field should match the Owner field when a video is entered in a contest.

As owner of a video, you can have finder rights transferred to you.

Simply click "Request Finder Rights" and an e-mail will be sent to the current Finder of the video. The Finder may then transfer
rights to you. If he or she does not, bear in mind that an Administrator will see the refusal of your request and will be able to
review it.

People work hard on educational videos, and we want to encourage them to make more!
